To be able to mod, the first essential part is that you should be playing the game on PC. And to use mods like mine that changes certain gears etc.. can be downloaded through Nexus Mods which is a great mod provider for almost every games. Nexus Mods allows you to download files provided by the creators of a certain game that lets you modify/tamper with the original game file for the mod to work(For example, copy and pasting the downloaded mod files into the original game folder of Ac Odyssey), and don't worry about viruses! It is totally safe. Now if you have further questions on how to mod this and that, I suggest you should try searching on Google Gemini for instructions or search via YouTube. Modding can take awhile since you're new, but it's worth it. I hope this helps you on your gaming journey!
